Dual Power Transfer Switch 4P

Dual Power Transfer Switch

A. The PC-class series isolated Dual Power Transfer Switch is a perfect integration of switch and logic control, truly realizing electromechanical integration. The Dual Power Transfer Switch is equipped with a series of advanced functions such as voltage detection, frequency detection, communication interface, electrical and mechanical interlocking, and has multiple operation modes: automatic, electric remote control and emergency manual control.

B. The logic control board, as the "intelligent brain" of the Dual Power Transfer Switch, precisely manages the operation of the motor and gearbox. The motor drives the switch spring to store energy, and with the instantaneous release acceleration mechanism, it can quickly connect or disconnect the current and efficiently complete the circuit conversion. Moreover, safe isolation is achieved through clearly visible status, which greatly improves electrical and mechanical performance.

1. Fully automatic function: It turns off when the common power supply is cut off. The Dual Power Transfer Switch will automatically switch to the backup power supply; when the common power supply returns to normal, the switch will automatically switch back to the common power supply, without manual intervention throughout the process.

2. Force setting "0" function: Activating the force setting "O" button switch will cut off the dual power supply. This function can be used in special circumstances, such as equipment maintenance and emergency power outage.

3. Remote control function: That is, remote control, press the "i" gear button; common power supply operation; press the "ll" button to start the backup power supply; press the "0" button to cut off the dual power supply.

4. Function selection and wiring: Users can select the corresponding switch function according to actual needs and perform wiring operations according to the corresponding function. When placing an order, please be sure to indicate the model of the Dual Power Transfer Switch, current specifications and required functions, so that we can provide you with accurately adapted products.

1. Advanced electromechanical integration design: The (PC-class) series isolated dual power automatic transfer switch is a crystallization of the in-depth integration of switch technology and logic control, truly realizing electromechanical integration. The Dual Power Transfer Switch integrates a series of advanced functions such as voltage detection, frequency detection, communication interface, electrical and mechanical interlocking, and supports three operation modes: automatic, electric remote control and emergency manual control.

The logic control board is like the "intelligent brain" of the switch, precisely managing the operation of the motor and gearbox. The motor drives the switch spring to store energy, and with the instantaneous release acceleration mechanism, it can quickly connect or disconnect the current and efficiently complete the circuit conversion. At the same time, safe isolation is achieved through clearly visible status, which significantly improves electrical and mechanical performance.

2. Exquisite appearance and reliable performance: The overall switch adopts a unique marble-shaped design, which is not only small and exquisite, but also strong and durable. The shell of the Dual Power Transfer Switch is made of special materials, which has strong dielectric properties, can effectively isolate current and resist external interference. Its excellent protection ability and reliable operation safety enable it to work stably in various complex environments.

3. Excellent electrical performance and load adaptability

High-specification electrical parameters: The rated voltage of the Dual Power Transfer Switch covers 380V/400V three-phase four-wire system, and the rated current range is 63A~2500A, which can adapt to load requirements of different power levels; the rated short-time withstand current (Icw) reaches 50kA/1s, which can effectively resist the current impact during grid short-circuit faults and ensure the safety of the Dual Power Transfer Switch itself and the line.

4. Multiple safety protection designs

(1) Mechanical and electrical double interlocking: Mechanical interlocking uses a gear linkage mechanism to force interlocking to ensure that the two power contacts cannot be closed at the same time; electrical interlocking uses a logic control board to achieve power status interlocking. Double protection avoids the risk of short circuit caused by parallel operation of power supplies, and the interlocking reliability reaches 99.99%. ​

(2) Emergency manual operation: The Dual Power Transfer Switch is equipped with an independent manual operating handle. In case of power failure or control circuit failure, the power supply can be forced to switch mechanically to ensure emergency power supply (such as fire load).

(3) Overload and short-circuit protection (need to cooperate with external circuit breakers): As a PC-class switch, although it has no built-in protection function, it supports linkage with upstream circuit breakers (such as molded case circuit breakers), and sends fault signals through the logic control board to realize system-level protection cooperation.

Q: How to choose between PC-class and CB-class Dual Power Transfer Switches?

A: PC-class is suitable for scenarios where power interruption is not allowed (such as hospital operating rooms, data centers), focusing on fast switching (50-250ms), and requires external short-circuit protection devices (fuses or circuit breakers).

CB-class is suitable for scenarios requiring short-circuit protection (such as industrial production lines), integrating circuit breaker functions, but the switching time is longer (2000-3000ms). You can choose according to actual needs and the characteristics of the application scenario.

Q: Does the installation of the Dual Power Transfer Switch require professionals?

A: It is recommended to be installed by certified electricians. When wiring, be sure to ensure that the neutral wire (N) is correctly connected to the phase wire to avoid misjudgment by the frequency converter. At the same time, an isolating switch must be configured at the incoming end to meet the safety requirements during maintenance and ensure the personal safety of operators.

Q: How to maintain the Dual Power Transfer Switch to extend its service life?

A: Test the switching function monthly, clean the dust on the shell, and check whether the contacts are oxidized. Each year, the manufacturer's engineers will calibrate the mechanical interlock, upgrade the frequency converter program, and replace worn parts.
